Geoenvironmental compartment in campo maior complex, PI: an ecologic tension area

Abstract

The researched region, located in ecological tension area, was subjected to geo-environmental compartmentalization of its units, according to presupposed geo-systemic theories. The vegetation, in "cerrado island around termite hills", configures physiognomic types with abrupt or gradual contacts, installing themselves in soils subjected to lateritization and ironization processes. The relations between soil, vegetation, structure, floristic and diversity were analysed in 8 parcels (20m x 50m, each).

Ecotone; lateritization; micro-relieves
